Description

Electronic traffic sign

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic guidance display apparatus, and more particularly, to an electronic traffic guidance display apparatus for inducing safety walking of a pedestrian passing through a construction site, as well as inducing a safety passage of a vehicle in a road traffic obstacle section.

In the prior art, the guidance display device draws and displays certain letters and figures on a wooden board as a color to induce the safe passage and walking of a person or a vehicle, or a bulb lamp through a power cable 2 on a predetermined panel. The display device was arranged (see Fig. 1) at the boundary between adjacent roads and sidewalks by arranging only at the left and right arrows (1).

In addition, a construction vehicle is supported and works when a construction for maintenance, repair and safety management of ancillary facilities such as road, electric work, roadside pruning, etc. is performed in a road section where the vehicle is always operated.

At this time, the vehicle was carried out by attaching a predetermined panel in which the bulb-type lamps are arranged only with the marks such as '→', '←', '↙' as described above in the vehicle. Most of these bulb lamps operate as a method of blinking or always lighting using a yellow lamp to inform vehicle drivers and pedestrians.

However, the conventional traffic guidance display device using the bulb lamp has a life of the bulb lamp is 1000 hours or less, and there is a limit in various signs suitable for road traffic conditions. In addition, this bulb type lamp has a maximum power consumption of 910 W (24 V / 25 W * 26), an average power consumption of 490 W (35 W * 14) when the left and right arrows are displayed, and its brightness is weak. . In addition, there is a problem that the attention effect is lowered simply by displaying only a yellow bulb lamp.

Accordingly, the present invention for solving the above problems is red (RED), green (Green) and mixed colors of yellow (AMBER), and red (RED), green (Green), blue (BLUE) natural color of light emission By using a display board equipped with a diode, various traffic guidance signs are displayed to increase the alerting effect, consume less power, and adjust day and night brightness to eliminate driver's visual disturbances, and to display graphics, text, and colors. And it is an object to provide an electronic traffic guidance display device that makes it easy to identify the effect.

In addition, another object of the present invention is to provide a removable guide display device that can be attached to and detached from a construction vehicle and a stand-type guide display device that can be installed upright at a predetermined position of the construction site.

Wireless operation unit 52 for wirelessly inputting alphanumeric input data for display, and a transformer 62 installed in an electronic control box or in a field office to supply AC power by converting AC power at the field office. (Or generator).

In addition, when the removable traffic guide display device is attached to a desired position of the vehicle, the DC power supply 62 is supplied from the generator in the vehicle.

In addition, the configuration of the electronic control box 100, the battery charger 120 for charging the battery (Battery) by receiving the DC power supplied from the vehicle power or transformer, the LED sign 10, the warning light A battery 130 for supplying direct current (DC) power to the 20 and the work lamp 30, an inverter / DC 140 for converting to a direct current power corresponding to the operation of the beacon and the work lamp, and the supplied direct current An audio amplifier 150 that is operated by a power source and amplifies a sound of a person input through a microphone and outputs the sound to the speaker, and a guide light control data and traffic inputted through the wired operation unit 51 or the wireless operation unit 52. Receiving light (20) by receiving color control data of red, green, and mixed colors yellow (AMBER) or red, green, and blue (BLUE) related to the guide sign And operation of the work lamp 30 and of the LED sign 10. It is composed of the electronic control unit 110 for controlling its display.

In addition, the internal structure of the electronic control unit 110 includes red color, green color, and mixed color color (AMBER) or red color (RED), green color, and blue color). And a data distributor 111 (referred to as R, G, and B in FIG. 4A) for receiving and distributing control data such as guides, and receiving control data such as guide lights distributed through the data distributor 111. The control signal generator 112 for generating a signal for controlling the on / off operation, and the plurality of red color, green (BL), blue (BLUE) natural color data of each of the plurality provided on the LED display board It consists of a red controller 113, a green controller 114, and a blue controller 115 that control the on / off of the LEDs.

Referring to the accompanying drawings, the operation of the present invention according to the configuration as described above are as follows.

First, a description will be given by taking the detachable and wearable traffic guidance display device shown in Fig. 2A as an example.

Accordingly, the battery 130 is charged in the battery charger 120 provided in the electronic control box 100. The DC 24V is supplied from the charged battery 130 to the LED display board 10 and the audio amplifier 150. At this time, the DC 24V discharged from the battery is down (down) to a predetermined DC voltage in the inverter 140 is supplied to the beacon 20 and the work lamp 30 to make an operable state.

As described above, after the DC power is applied to the electronic control box 100 and the LED display board 10, the user inputs traffic guidance display data using the wired operation unit 51 or the wireless operation unit 52. In this case, the traffic guidance display data that can be input by the user includes data such as figures, texts, blinking control, color, guide light on / off control, and the like.

As such, when the user inputs data, the data distributor 111 of the electronic controller 110 distributes the data. According to the distributed data, the color controllers 113, 114, and 115 control the on / off of the red, green, and blue LEDs of the LED sign 10 to display the traffic guidance situation as shown in FIG. This allows the driver to drive the vehicle safely.

In this case, two or more characters such as 'under construction', 'under construction', 'dangerous', 'telephone construction', 'narrowing down', and the like are displayed at intervals of 1 to 2 seconds. In addition, the guide display may be flickered by adjusting a clock applied to each color controller 113, 114, 115 according to a user's manipulation.

In addition, when the left and right arrows shown in FIG. 5 are displayed, the average power consumption of about 490W is consumed by using the conventional bulb lamp (35W * 14). The average power is about 200 W or less, which is about 1/5 or less since only the used and actually displayed part is turned on. At this time, the brightness of the LED is stronger than the conventional bulb lamp, so the guide signs are clearly visible even during the day.

On the other hand, in the above-described electronic control unit 110 controls the on / off of the beacon 20 and the work light 30 in accordance with the control data input from the wired operation unit 51 or the wireless operation unit 52, the driver by the warning light Or call attention to pedestrians to prevent accidents in advance, and turn on work lights to ensure safe work at night work.

Next, the stand type traffic guidance display apparatus according to the second embodiment of the present invention has the same function as the detachable and detachable traffic guidance display apparatus, but is installed in a place where an AC power source such as an on-site office can be obtained (or The difference is that the DC power converted by the transformer 62 inside the electronic control box is provided through the battery charger 120, and that a certain amount of portable battery can be used to facilitate the movement and installation of the device.

The present invention as described above has the following effects as compared to the traffic information display device using a conventional bulb type lamp.

Firstly, by using the LED, the power consumption can be consumed less, and the energy can be saved.

Secondly, traffic signs with various text, color changes, shapes, and effects can double the effect of drawing attention to drivers or pedestrians in construction areas, leading to safe driving of vehicles or safe walking of pedestrians. have.

Third, depending on the construction environment, it can be loaded onto trucks or mounted directly on the ground.
